The Wellcap-Gas provides:

• Strong protection for your 50mm monitoring wells

• Self locking option with additional stainless steel security bolt, using a special key tool or allen key

• Hangar cable holes on the bottom end of shaft

• Fully sustainable, made from recycled plastic waste

The Wellcap-GAS has a quick connect gas fitting and dust cap installed on the top, enabling gas in the well to be monitored or sampled with a gas instrument or suitable pump. The WellCapGas can also be locked in place with a padlock or by using a security screw or both for extra security. The WellCap - Gas has a partially hollow shaft that intersects a horizontal side hole near the bottom. This allows the well gas to be drawn in through the side hole and out the top. The side hole also serves to hang sampling or monitoring devices off the bottom of the cap while at the same time gas samples can be taken out through the shaft and out the gas quick connect fitting.
